Indian inland aquatic ecosystems. Microplastics (MPs) have been identified as emerging contaminants, potentially impacting public and ecosystem health. This comprehensive review discusses the current state of knowledge on MP contamination mechanistic process understanding in It highlights gaps regarding data methodological differences sampling sample processing that can lead to contrasting results. Most studies reviewed here provided evidence water, sediment certain indicator species ecosystems at specific locations times. Significant seasonal variations concentrations for pre-, during post-monsoon periods. We found only a few considered inherent spatio-temporal variability concentrations, intricate interplay with hydrological key parameters has largely overlooked. However, order improve our how MPs are transported within these (e.g., river networks) decide potential pollution mitigation, it is imperative link concentration physico-chemical characteristics information such flow velocity or discharge. will provide loads help establish loading functions needed better understand impacts

Microplastic pollution in the Ganga River: A state-of-the-art review of pathways, mechanisms, and mitigation

Water Science & Technology Water Supply, Год журнала: 2025, Номер unknown

Опубликована: Янв. 21, 2025

ABSTRACT Microplastic (MP) pollution in the Ganga River, a vital waterway sustaining millions, has become significant environmental and public health concern. This review employed systematic approach to examine MP utilizing comprehensive database search across Scopus, PubMed, SpringerLink. discusses multifaceted pathways through which MPs enter propagate within river ecosystem. Key sources include urban industrial wastewater discharge, agricultural runoff laden with plastic mulch contaminated fertilizers, inadequate solid waste management leading litter illegal dumping. Atmospheric deposition also plays role transporting from centers river. Riverine dynamics, influenced by natural flow sediment processes, facilitate downstream transport of these pollutants. The cultural religious significance contributes ritual practices mass gatherings. Ecologically, pose severe threats, affecting aquatic organisms ingestion bioaccumulation toxic substances, thereby disrupting biodiversity food chains. Socio-economically, this jeopardizes livelihoods communities reliant on Addressing contamination demands mitigation strategies. Effective solutions must integrate scientific understanding robust safeguard ecological socio-economic integrity River.

Impact of Minerals (Ferrihydrite and Goethite) and Their Organo-Mineral Complexes on Fate and Transport of Nanoplastics in the Riverine and Terrestrial Environments

Environmental Science & Technology, Год журнала: 2025, Номер unknown

Abundantly occurring minerals are detrimental in dictating nanoplastics (NPs) fate and transport the environment. However, natural scenarios, barely exist their pure phases. Minerals often associated with organic matter form organo-mineral complexes (OMCs), exhibiting different reactivity than mineral phase. In this study, we investigated impact of ferrihydrite, its weathering-originated secondary goethite, corresponding OMCs, i.e., organo-ferrihydrite (O-Fh) organo-goethite (O-Goe) on NPs mobility under varying environmental conditions (ionic strength, pH, river water). Results showed higher sorption capacity compared to respective OMCs for NPs, ferrihydrite (529.62 mg/g), O-Fh (439.08 goethite (823.64 O-Goe (688.88 mg/g). Zeta potential sedimentation kinetic studies suggested heteroaggregation coagulation goethite-NPs bimodal system. NPs-minerals/OMCs interaction mechanisms were confirmed by FTIR XPS analysis. Column experiments DLVO analysis revealed that minerals/OMCs coated sand retention bare quartz pore water chemistry. Ferrihydrite columns have shown maximum (>95%). Our study provides insight into how environmentally relevant phases thier aqueous terrestrial environments.
